Abstract (en)
[origin: US5374757A] A process for the organooxylation of beta -cyanoalkylchlorosilanes. The process comprises contacting in a film a beta -cyanoalkylchlorosilane with an alcohol capable of forming an ester with the silicon of the beta -cyanoalkylchlorosilane and thereby forming an equilibrium mixture comprising a ( beta -cyanoalkyl)organooxysilane and hydrogen chloride. The film is heated at a temperature sufficient to cause vaporization of the hydrogen chloride from the equilibrium mixture thereby increasing yield of ( beta -cyanoalkyl)organooxysilane in the equilibrium mixture. In a preferred process, the process is run in a falling-film type reactor or a wiped-film type reactor.
